Abstract Intestinal parasites have a serious health problem and frequently infect children in poor urban areas in developing countries. Some types of Cryptosporidium, Entamoeba and Giardia are amongst the most prevalent ones. The aim of this study was explore the distribution pattern of intestinal parasites and the ecological niche of Giardia lamblia in Ardabil Province. This was retrospective cross-sectional study, the officially registered statistics of health centers and hospitals in Ardabil University of Medical Sciences from January 2017 to December 2019 were used. The Kriging interpolation analysis was run to detect the high-risk areas of the disease in the province (P\0.05) by ArcGIS10.4.1 and to construct the ecological niche model of the G.lamblia parasite, analyzed by Maxent3.3 software. Totally of 238 cases of intestinal parasite were reported during the study period, 77.7% of which were males and 22.3% females. Seven types of intestinal parasites were prevalent with G.lamblia species (79.4%) being the most and Entamoeba histolytica species (4%) the least prevalent one. There was one hotspot in the province in the center with an incidence risk of 41–45.5%. The most important climate and environmental factors affecting the ecological niche of G.lamblia are Bio16, Bio3, and the NDVI. G.lamblia is the most prevalent intestinal parasite in Ardabil Province; moreover, one important hotspots was also detected in the province that can provide useful information regarding the management and control of this parasite.
